ROAD DRAG.

To all whom it may concern L Be it known that I, JOSEPH W; HRUsxA, a citizen of the United States, residing at Mankato, in the county of Blue Earth and State of Minnesota,-have invented certain new and useful Improvements in Road Drags; and I do declare the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in Another object is to provide a road planer which embodies a runner and both a main and a supplemental scraper bar associated therewith in a novel manner to effectively remove any mounds and other projections in the roadway, deposit some of the earth in the depressions, and discharge .the remainder at the center of the highway.

With the foregoing in View, the invention resides in the novel construction and arrangement of parts hereinafter described and claimed, the descriptive matter being supplemented by the accompanying drawin s.

Figure 1 is a perspective view of a road planer constructed in accordance with my invention.

Figure 2 is a top plan view.

Figure 3 is a sectional View as indicated by line 33 of Fig. 2.

Figure 4 is a detail side elevation showing the manner of forming the front ends of the runner beam and the two scraping beams.

In the drawings above briefly described, the numeral 1 designates an I-beam forming a runner which is adapted to travel along the center of a roadway. Spaced laterally from the I-beam 1 is a second I-beam 2 which Specification of Letters Patent. Patented F b 7" 1922 Application filed December 16, 1920. Serial No. 431,209.

is inwardly spaced from the intermediate portion of the I-beam 1 to form an outlet throat 6 for the earth or the like scraped from the roadway by said beam-5.

For connecting the several beams, I pref-:

er ably employ four transverse channel bars 7, 8 -9 and 10 respectively. The bar 7 extends across the front ends of the three beams 1, 2 and 5 and is secured by bolts or the like 11 thereto; the bar 8 extends from the front end of the beam 1 across the beams 5 and 2, at substantially right angles to the last named beams, and is secured in place by bolts. 12; the bar end of the beam 1 across the rear end of the ntermediate beam 5 to a point near therear end of the beam 2, and bolts 13 are employed for securing it in place; and the bar 10 is relatively short and connects only the'rear end portions of thetwo beams 1. and 2, bolts let being employed for securing these parts together. Thisarrangement of the bars 7, 8, 9 .and.. 10 forms an extremely rigid con- -onfa line extending longitudinally of .the I earth scraped from the surface of the road 9 passes from the front beams'l, 2 and 5, even though ordinary bolts are used forsecuring the several parts to-v gether, but it will be understood that if it is not desirable to ship or transport the scraper in a knocked down condition, rivets may be substituted for the bolts.

The front ends of the three beams 1,2 and 5, are preferably beveled as indicated at 15 and the bottom flanges 16 of these beams are bent upwardly along the bevel as shown. In forming this construction, the details illustrated in Fig. 4 ma be followed. The lower portion of the we 17 is formed with a V- shaped notch 18 whose lower edge is flush with the upper surface of the flange 16, while its upper edge forms the bevel 15. After notching the web 17 in this manner, the flange 16 is bent upwardly along the bevel 15 and may be welded or otherwise secured. This forms a simple and inexpensive, yet a highly efficient and desirable manner of constructing the front ends of the several beams, and although this detail is preferably followed, other adequate constructions could of course be used.

A suitable chain 19 is connected at its ends to the front ends of thevbeams 1 and 2, and is.-

e nipped with an adjustable draft link 20 w ich may be so positioned along the length; of the chain as to cause the runner 1 to. travel ,on ,a strictly straight line alon the center of the roadway. The scraping eam 2 then extends entirely'to' the edge-of-the road and this beam, together with thebeam 5, effectively planes J or scrapes the surface of-the roadwayso that all projecting sur-- facesaarei removed and the hollows filled, any ofithematerial which is not deposited in the hollows,: being discharged throughfollow-it's power. Whenever the device must beca-rried from onepoint on-aroadwayto a ratherremote point-,itanay be-easily knocked down, load'ed on a motor-truck or the like, carried tothe desired point, and then again vantage ininitially shipping the "devicefromthe-fa'ctory at which it is constructed.

By-using I-beamsand channel bars in the construction of the drag, it is not only extremely" rigidbut will possess sufficient weight to. operate effectively, without the necessity ofproviding a platform to carry a load 'to'weightthe' machine down.. Furthermore, themetal construction insures long life, even though subjected to extremely rough;use-.-andtherflangeswof the several longitudinal beams form effective cutting edges tooactegon the surface of the roadway, withonthowever digging into and impairing the road belowthe surface.

Since probably the best results may be obtained-fronr-=the several details disclosed, such details may be followed if desired,but I Wish it understood that within the scope ofthe invention as claimed,"numerous minor changesmaybe made.

Iclaim': r

A road planer comprising 'anJI-beam forming'ja runner-adapted to travel parallel with a a the edges of a road, a second I beamforrning a scraper diverging forwardly with respect to'saidrunner forming beam. with its rear end spaced directly inrear of said runner forming beam, on a line extending along the latter, a third I-"beam forming a second scraper spaced-inwardly from andparallel with" the first named scraper forming beam with its rear end spaced inwardlytfr'om the intermediate portion of said runner forming beam, a; channel bar extending across the front ends of the three beams, a second channel barextending from the'front end ofthe runner forming beam across the otherbeams at substantially right angles to the latter and'secured to' allZOfsaid beams, a third channel bar extending from. the front end of r the runner forming beam to a pointnearthe rear end oftheofi'rst named scraper forming beam andsecured to all of the beams, and a relatively short bar connecting the rear end of 'said'runner'forming beam with the'corresponding end offsa'idjfirst named scraper forming beam; V

In testimony whereof 'Ihave hereunto set my hand.
